Smith, Washington, Conn, assignor to The Great Northwestern Connecticut Window Corporation, a corporation of Qonnectieut Filed Sept. 3, P363, Ser. No. 366,234 6 (Ilaims. (Ci. 2G-42) This invention relates in general to windows for dwellings, offices, factories, and the like; and, more particularly, it relates to windows which may be reversed within their frames.

An object of this invention is to provide an unpartitioned window of almost unlimited height and length which may still be easily opened and cleaned.

Another object of this invention is to provide a window which may be easily reversed in its frame so that it may be completely cleaned from the inside.

Yet another object of this invention is to provide a window which may be more rapidly reversed within its frame for cleaning, the rapid reversal of the window minimizing heat losses while cleaning the window during cold weather.

Still another object of this invention is to provide a window which will reverse in its frame for cleaning and which does not project while being reversed beyond the window frame so that exterior storm windows and screens need not be removed or disturbed.

A further object of this invention is to provide a picture type window which may be slightly opened for natural ventilation.

Yet a further object of this invention is to provide a window which may be automatically reversed within its frame with a single motion of a handle.

An additional object of this invention is to provide a safer window in which outside miantenance is completely eliminated.

Many other objects, advantages and features of invention reside in the particular construction, combination and arrangement of parts involved in the following embodimerit of this invention and its practice as will be understood from the following description and accompanying drawing in which the several reference characters refer to same or like elements and wherein:

FIGURE 1 is an elevational view from the inside of the broken away side of a window constructed according to this invention;

FIGURES 2, 3 and 4 are sections taken 'on'the lines 22, '33, and 4- 4, respectively, of FEGURE 1;

FIGURE 5 is a side view of the window frame with the window open for'purposes of'ventilation;

FIGURES 6' and 7 are sections taken on lines 6'6 and 77, respectively, of FIGURE 5;

FIGURE 8 is a side view of the window frame of this invention with the swing frame pivoted outward prior to the automatic reversal of the glazed frame;

FIGURE 9 is a side view of the window frame with the swing frame extended to its maximum with the glazed frame being automatically reversed within the swing frame; and,

FIGURE 10 is a transverse vertical section through an upper fragment of the window taken near one side of the glazed'frame with the glass removed, the swing frame and the glazed fram'ebeing shown in the same positions relative to the structural frame as in FIGURE 9.

Referring to the drawing in detail, FIGURES l, 2, 3 and 4 show a structural frame, generally designated by the numeral 23. Frame 24 has side members El, a bottom member 22 and a top member 23 forming a rectangular structure. Extending inward from the rearmost portions of the bottom and top members 22 and 23 are upwardly and downwardly projecting flanges 24 and 25. The side 3,154,822 Fatente'd Nov. 3, 1964 members 21 have the deeper inward projections 26 which have a raised bead or ridge 27 formed near their inner edges. A sill 28 extends inward from the bottom member 22 and top and side moldings 29 and 30 project upward and laterally from the top member 23 and the side members 21.

The window of this invention may be prefabricated to be sold completely within a structural frame ready for installation in a dwelling or other building. Thus the structural frame 2% is designed to fit within a given opening and presents a finished and trimmed appearance.

Referring further to FIGURES 1, 2, 3 and 4, fitting within structural frame 20 close to the side members 21 and the bottom and top members 22 and 2 3 is the swing frame 31. Swing frame 31 has the side members 32 and the top and bottom members 33 and 34 which form a rectangle extending inside and adjacent to the side members'fil and the top and bottom members 23 and 22 of the structural frame 20.

Within the rectangulm swing frame 31 is disposed the rectangular pivotally mounted glazed frame 35 having side members 36 and top and bottom members 37 and 33. T..e side members 38 contain vertical grooves 39 on each side. The top and bottom members 37 and 38 have projectionsil and llextending horizontally from both their sides. When the window is closed, the projections 45 and 41 extend under and over the flanges and 24. The beads 2'7 extend within the grooves 39. Thus, this window provides a very good weather seal when closed.

Glass 42 is secured within the pivotally mounted glazed frame with any suitable glazing material as. The structural frame as, the swing frame 31, and thepivotally mounted glazed frame '35 may be made of aluminum, Wood, or any other suitable building material.

As shown in FIGURES l, 5 and 6, the bottom member 34 of the swing frame 31 has a handle 44 fixed to it. Vfnen handle 34 is pulled outward, swing frame 31 and glazed frame '35 swing forward as the slide brackets 45 each pivot about a pin 45. Each slide bracket 45 is fixed to'a side member 32 of the swing frame 31 by a pair of spaced apart fasteners 47 which extend through a slot 58 in each slide bracket 45. Thus the fasteners 47, which are free to slide in the slots i8, slidably secure the swing frame 31 to the pivotally mounted slide brackets 45.

The swing frame 31 and the glazed frame -35 would slide downward along the slide bracket :5,but' their downward motion is restrained by a pair of pivotally mounted links 49 which are pivotally secured at their lower'e'nds by the pins 54 and at-their upper ends by the pins 51. The pins 559 and 51 may be seen in FIGURE 10.

The lower rearwardly disposed outer edges of the swing frame 3l'have retaining bars 52 pivotally fixed at their lower ends by pins 53. Portions of the swing frame slide members 32 may be cut away to-accommodate the retaining bars 52 which retract against the side members 32when not in use. As shown in FIGURE 5, when it is desired to open the window for ventilation, the retaining bars 52 maybe pivoted rearwardly to be pfopped against the structural frame '26 and hold the swing frame and the. glazed frame contained within it in an opened position. The retaining bars 52 may be set to allow the window to be opened to any desired degree.

When the glazed frame 35 is to be reversed for cleaning, the retaining bars 52 are placed in the retractedposition along the swing frame 51. Handle 44 is then urged further forward as shown in FIGURES 8 and 9. As handle 4 moves forward, the links 49 allow the swing frame to slide downward in the slide brackets 45. The glazed frame 35 is rotatably and pivotally mounted in the swing frame 31 by two pins Two short studs 55 are fixed to each side of the glazed frame 35 close to the pins 54.

3 The swing frame 31 may be cut away for a slight distance on either side of the pins 54, as shown in FIGURE 1, to allow the glazed frame and the projecting studs to rotate within it.

As may be further seen in FIGURES 8, 9 and 10, a pair of long flexible hooks 57 are pivotally secured by pins 56 at their upper ends. The lower portions 58 of the hooks 57 extend below the studs 55 when the window is in the closed position. As the swing frame 31 and glazed frame 35 move downward along the slide brackets 45, the lower portion 58 of each book 57 engages the lowermost stud 55 to start the glazed frame 35 rotating about pin 54 within swing frame 31. The inertia of the glazed frame 35 causes it to complete one-half of one revolution and return to its original but reversed position within the swing frame 31. The hook 57 is urged upward so that it may engage a stud 55 in the manner which has been described by means of a retaining loop 59 fixed near the upper end of a link 49.

When the handle 44 is urged upward and backward to return the swing frame 31 and glazed frame 35 into the structural frame,'the upwardly and rearwardly bent tips of the hooks 57 override the studs 55 so that the swing frame and the glazed frame may return to the position shown in FIGURE 1 or 5. Thus, it may be seen that the glazed frame 35 may be reversed automatically and rapidly within the structural frame 20 by merely grasping handle 44 and, with a steady rapid motion, urging it forward and downward and then back upward and rearward. This accomplishes a. smooth and rapid reversal of glazed frame 35.

If it is desired, a pair of tension springs 60 may be provided to extend between the structural frame 20 and the links 49. The use of springs 60 allows the swing frame 31 and the glazed frame 35 to maintain a more stable condition of static balance in some positions.

If the hooks 57 and the studs 55 are not provided, this invention may be practiced by rotating the glazed frame 35 manually when the swing frame 31 is extended into the position shown in FIGURE 9. Further, while the window has been shown and described with the swing frame pivoting outward from the top of the structural frame, the entire window could be inverted or placed on its side and still be used in substantially the manner which has been described. a

While this invention has been shown and described in the best form known, it will nevertheless'be understood that this, is purely exemplary and that modifications in the construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention except as it may be more limited in the appended claims wherein, what is claimed is:
